SANTA ANA, Calif. (AP)  A 31-year-old Orange County woman has been sentenced to more than two years in federal prison for her role in a scheme to bilk health insurers by submitting claims for unnecessary procedures.

The Orange County Register reports (http://bit.ly/1Mou675 ) Vi Nguyen (Win) was also ordered Friday to pay $2.6 million in restitution. The Placentia resident had pleaded guilty to mail fraud.

Prosecutors say Nguyen and two co-defendants promised free or discounted cosmetic surgery to patients who agreed to undergo unnecessary procedures  such as colonoscopies  at an Orange County surgery center.

They submitted millions in claims. Once insurers paid, the patients were given tummy tucks, liposuction and other cosmetic procedures that typically aren’t covered by insurance.

Theresa Fisher of Tustin and Lindsay Hardgraves were sentenced last month.
